Abstract
The invention provides a sealed connection device for a compressed air aluminium alloy pipeline. The sealed connection device overcomes the shortcomings that an existing connection device is complex in structure and small in sealing area. The sealed connection device comprises a metal shell, elastic membranes, a rubber sealing tube and locking bolts, wherein the metal shell is formed by two semicircular shell bodies in a paired mode, and the two semicircular shell bodies are connected and locked through the bolts. The sealed connection device has the characteristics of the simple structure and the large sealing area.
Description
Technical field
The present invention relates to a kind of sealing and connecting device compressing air aluminium alloy pipeline。
Background technology
The pipe joint being currently used for connecting compressed air hose has multiple。The existence of existing pipe joint general problem is that the parts of joint are too many, structure is complicated, sealing relies solely on rubber o-ring and seals, the area sealed is only small, simultaneously because there is coast of paint on the surface of aluminium alloy pipeline, paint and rubber o-ring can As time goes on and gradually aging, it is easy to cause compressed-air actuated leakage。For the sealing and connecting device of the compression air aluminium alloy pipeline of this present invention, simple in construction, sealing area is big, reduces the probability that compression air is revealed。
Summary of the invention
The technical problem to be solved is that existing compressed air hose joint part is many, and structure is complicated, the problem that sealing area is little, it is an object of the invention to provide a kind of simple in construction, the connecting device that sealing area is big。
In order to realize above-mentioned purpose, present invention employs following technical scheme:
According to embodiments of the invention, a kind of sealing and connecting device compressing air aluminium alloy pipeline is provided, it is characterized in that, the sealing and connecting device of described compression air aluminium alloy pipeline, constitute including metal shell 1, flexible sheet 2, rubber sealing tube 3 and clamping screw 4, wherein metal shell 1 is made up of two semi-ring housing pairings, is bolted locking between two semi-ring housings。
According to embodiments of the invention, it is preferable that flexible sheet (2) is coated on rubber sealing tube (3) outside, and flexible sheet (2) is wrapped up by metal shell (1)；The bosom of rubber sealing tube (3) has tongue；Flexible sheet (2) has arcuate indentation；Metal shell (1) is made up of upper shell (5) and lower house (6), and upper shell (5) and lower house (6) connect locking by bolt (4)。
The beneficial effect that the present invention reaches:
The sealing and connecting device of the compression air aluminium alloy pipeline of the present invention, simplifies sealing and connecting device, increases the area of sealing simultaneously, reduce the probability of leakage。

Detailed description of the invention
The sealing and connecting device that the present invention compresses air aluminium alloy pipeline below in conjunction with accompanying drawing is described in detail。Following example are only for explanation technical scheme clearly, and can not limit the scope of the invention with this。
Fig. 1 be according to the present invention compress air aluminium alloy pipeline sealing and connecting device embodiment profile。As it is shown in figure 1, this sealing and connecting device is made up of metal shell 1, flexible sheet 2, rubber sealing tube 3 and clamping screw 4。
Metal shell 1 is made up of semicircular upper shell 5 and lower house 6 two parts, upper-lower casing all fluted 7, during use, groove 7 plays the role of positioning with the tongue cooperation of aluminum pipe, upper shell 5 there is bolt hole, having the bolt hole of correspondence on lower house 6 and be threaded, upper shell 5 and lower house 6 connect locking by bolt 4。Flexible sheet 2 is fabricated by by elastomeric material, and has arcuate indentation as shown in Figure 5；Rubber sealing tube 3 is internal tongue。
First flexible sheet 2 is enclosed within aluminum pipe during use, then two tube and pipe of aluminium alloy enemies are inserted in rubber sealing tube 3, secondly the flexible sheet 2 being enclosed within aluminum pipe is enclosed within rubber sealing tube 3, then corresponding good to upper shell 5 and lower house 6, finally tightens 4 bolts。
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the technology of the present invention principle; can also making some improvement and deformation, these improve and deformation also should be regarded as protection scope of the present invention。
